padgett Posted November 30, 2020 Share Posted November 30, 2020 Probably a stuck blend door. Is mechanical, lever is on top of "programmer", and rod goes behind the glove box. Link to comment Share on other sites More sharing options...

Look at the top control bar and click on the "How to" section. Then click on "Heat and A/c" you will see it drop down and then you can click on control panel cleaning.

2seater Posted December 1, 2020 Share Posted December 1, 2020 I have had to do the cleaning a couple of times in more than 25 years of ownership. Needs to be done when you lose a function or two on the climate control. In my case I can only make the temperature go down, not up 😣 Link to comment Share on other sites More sharing options...
Jim Posted December 2, 2020 Share Posted December 2, 2020 Much easier way------- Take a pencil with an eraser or just use your finger and punch the bad button sort of hard. This usually dislodges the dirt and it will start working again. Link to comment Share on other sites More sharing options...
